Improvement in cultivators



PATENT OEEICE.

THOMAS E. O. BRINLY, OF LOUISVILLE, KENTUCKY.

IMPROVEMENT IN CUL'IV'IVATORS.

Specification forming part of Letters Patent No. 116,147, dated June 20, 1871.

To all rwhom it may concern.-

Be it known that I, THOMAS E. C. BRINLY, of Louisville, in the county of Jefferson and State of Kentucky, have invented a certain Improvement in ShaftCultivators; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawing making part of this specification, in which- Figure l is a perspective view of the im-` proved cultivator. Fig. 2 is a vertical longitudinal section.

The same letters of reference are employed in both figures in the designation of identical parts.

This invention, having for its object the improvement of what are termed shaft-plows or cultivators, consists in a novel construction and arrangement of the parts, as will be generally described in the following description and specifically pointed out in the claim.

The frame of the cultivator is of rectangular form, and each, side beam is extended forward a suflicient length to form one thill, A, ofthe shafts. The handles B are secured upon the rear end of such beams. The shovels, three in number, are hun g to the longitudinal beams, arranged parallel to the side beams, and fastened between double cross-beams C C and C C at each end ofthe frame. The central one of these longitudinal beams, marked D, is permanently iiXed in place, and to its forward end the single-tree D1 is pivoted upon a stout bolt suitably stayed in the ordinary manner. The connection of this beam with the side beams of the frame is further stren gthened by a triangular stay, D2, as clearly indicated in Fig. l, and an additional cross-bar,

The beams E and F are adjustable laterally in the double cross-bar, the latter being provided with a series of bolt-holes for that purpose, as shown. The shovels G are suspended from their respective beams D E F by iron standards H, which are made of fiat iron, doubled so as to form a slot from the beams down to the lower extremity ofthe standards. The slot is made of suflicient width on top to receive the beams, to which the standard is 4then pivoted by means of a bolt. The shovels,

which may be double-pointed ones, as shown, are secured to the standards by two bolts, which pass through the shovels, and, projecting through the slot in the standard, are clamped thereto by nuts, as clearly indicated in Fig. 2. The shovels can thus be readily re versed or adjusted up or down on the standards. The shovels and standards are held in the proper position by stays or braces I, which are, at one end, pivoted in the slot of the standards, and, extending obliquely upward, pass through slotsz in theV beams, to which they are then secured by pins, by preference wooden pins, so that should the shovel come in contact with a root the pin may break and allow the standard to swing back and prevent its breakage. The upper ends of the braces have a number of pinholes for the purpose of adjusting the shovels at any inclination desired. The depth to which the shovels shall enter the earth is regulated by asmall wheel, K, running 011 top of the ground in front of them. This wheel is hung by its journals in a frame, L, which consists of two bars of iron coming in contact just above the fork, with which they embrace the wheel, and thence diverging to be pivoted, respectively, to the side beams of the frame. A brace, M, similar to the braces I, serves to hold the frame and wheel in place, and regulates its height with reference to the points of the shovels.

What I claim as my invention, and4 desire to secure by Letters Patent, is

The herein-described shaft-cultivator, composed of a rectan gul ar frame, the elongated si de beams of which form the shafts A A, and carry at the rear the handles B B, iiXed central beam-D tied to the side beams by triangular stay D2, laterally-adjustable beams E and F, slotted iron standards H, which are provided with adjustable shovels G and adjust-ably connected to their respective beams D E F by braces I, and the gauge-Wheel K, hung in a frame, L, whichl is suspended from the side beams of the main frame, and raised or lowered by means of a brace, M, passing through the beam D, all the parts being constructed and arranged substantially as set forth.

In testimony whereof I have signed my name to this speciication in the presence of two subscribing witnesses.
